应用Ｘ射线衍射分析和穆斯堡尔谱学研究了Ｆｅ７３．５Ｃｕ１Ｎｂ３Ｓｉ１３．５Ｂ９非晶合金的纳米晶化过程．Ｆｅ７３．５Ｃｕ１Ｎｂ３Ｓｉ１３．５Ｂ９合金在５００～６００℃温度范围内分别退火１ｈ，可形成纳米ＤＯ３结构的ＦｅＳｉ相和剩余非晶相。随着退火温度的升高，有更多的ＦｅＳｉ相析出。在５００℃等温退火中ＦｅＣｕＮｂＳｉＢ合金出现二阶段纳米晶化过程。
The nanocrystallization of Fe73.5Cu1Nb3Si13.5B9 amorphous alloy was studied by X-ray diffraction and Mossbauer spectroscopy. Fe73.5Cu1Nb3Si13.5B9 alloy were respectively annealed at 500-600 ℃ for 1h to form the FeSi phase with nano-DO3 structure and the remaining amorphous phase. As the annealing temperature increases, more FeSi phase precipitates. The second stage nanocrystallization of FeCuNbSiB alloy occurs at 500 ℃ in isothermal annealing.
